HAROLD J. BELL, OF GLOUCESTER CITY, NEWV JERSEY, ASSIGNOR TO THE VVELSBACH INCANDESCENT GAS LIGHT COMPANY, OF NEW JERSEY.

GAS-GOVERNOR.

SPECIFIGATION forming part of Letters Patent No. 400,172, dated March 26, 1889.

Application filed July 2, 1888. Serial No. 278,735. (No model.)

To all whom it may concern.-

Beit known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Gas-Governors, of which the following is a specification.

My invention consists in a gas-governor or gas-regulating burner having the peculiaril0 ties of construction hereinafterdescribed and claimed.

In the annexed drawings, Figure 1 is a vertical section of a gas-regulating burner embodying my invention. Fig. 2 is an elevation of the lower and internal part of the regulator or governor. Fig. 3 is a plan of the same. Fig. 4 is a perspective of the floatvalve.

This gas-regulating device comprises abase,

l, which is externally screw-threaded for the attachment of an internally-screw-threaded shell, 2, that forms the upper and outer part of the device. The base 1 is formed with an internally-screw-threaded neck, 3, for attachment to a gas-fixture, and above this neck and communicating therewith is a tubular stem, 4, that is'closed at its upper end. Near the upper end of the tubular stem 4 are gasexits 5, which are controlled by a tubular 3 Valve, 6, that surrounds the stem 4 and is provided with gas-openings 7, that may be made to register with the gas-exits of said tubular stem. The tubular perforated valve 6 carries near its upper end, immediately above the openings 7, a disk-float, 8, the periphery of which is in contact with the vertical wall of a cup or annular chamber, 9, which surrounds the tubular stem 4, said stem and cup being integral with the base 1 4 of the device. The bottom of the cup or annular chamber 9 is inclined outward and upward, as shown in Fig. 1, and in this inclined bottom is a gas-exit, 10, which leads into an annular gas-passage, 11, that surrounds said cup.

In the base 1, opposite the opening 10, is a screw, 12, which can be adjusted inward or outward to regulate the quantity of gas admitted into the passage 11 to suit the capacity of the burner and the pressure of the gas. The shell 2 is cylindrical in form,.with a ii at top from which rises a nipple or pillar, 13, for the attachment of any suitable burner.

The gas that is admitted into the tubular stem 4 passes thence through the perforations or exits 5 and 7 into the cup 9, beneath the disk-float 8, and from the cup 9 through the opening 10 into the annular gas-passage 11, and then to the burner. If the pressure of gas in the cup or chamber 9 is excessive, the disk-float 8 and the tubular valve 6 will rise, and the lower portion ofsaid tubular valve will more or less cover the gas-exits 5, so as to automatically control the pressure at the burner.

It will be observed that the gas-exits 5 of the tubular stem 4 are located in an annular countersink or groove, let, formed in the outer surface of the said tube 4, so that no matter what lateral position the tubular perforated valve 6 may assume on the tubular stem 4: the flow of gas through the exits 5 and 7 will not be obstructed, as might otherwise occur by a partial rotation of the tubular valve.

In another application, Serial No. 27 8,737 of even date herewith, I have described and claimed a gas-regulator comprising a twopart shell having a tubular perforated stem,

a cup surrounding said stem and having an opening or gas-exit in its bottom, an adjust- 8o ing-screw for controlling the passage of gas through said opening, gas-passages thence to the burner, and a floatrvalve having a perforated tube that surrounds the tubular perforated stem, and such construction I do not v (late herewith. wit/h disk-float 8, suhsi'anixially as les('-,i'il)e(l. 1o

hat I claim is- In testimony whereof I affix my signature in In a gas-governor 01' gas-regulating burner, presence of two witnesses.

5 the combination of the base 1, having a tubular perforated stem, 4, and. a cup, fl, provided with an inclined perforated bottom, the shell 2, the annular gz'is-passage 11,1110 screw 12,

in my application, Serial No. 279,736,01 even l and the tubular perii'm'ated valve 6, provided l n. J. nic'ml. i 'Witnesses:
